The condensed financial information of the Company for the year ended December 31, 2020 has been revised to (i) reflect a reclassification adjustment on the presentation of cash flows between the Company and its subsidiaries within the Group. Such cash flows were previously inappropriately presented under the operating activities of the condensed financial information of the Company. The condensed financial information has been revised to properly reflect the cash flows from the Company to its subsidiaries as the investing activities amounted to US$38.6 million in FY20; and (ii) reflect a reclassification adjustment on the presentation of the amount due from entities within the Group from current to non-current in nature amounted to US$123.3 million in FY20 and the amount due to entities within the Group from current to non-current in nature amounted to US$3.9 million in FY20. Management considered the revision is immaterial, the impact of the revision was eliminated in consolidation, and there is no impact on the previously reported consolidated financial position, results of operations or cash flows.
